Nanny, quite rightly, is concerned about the number of cases of drink driving. She has warned us over the years about the dangers of driving, whilst under the influence; yet there is still a hard core of people who regularly take to the wheel, whilst under the influence.
Nanny is therefore trying a new preventive technique, in Scotland, to catch drink drivers before they take the wheel.
Should this prove successful, she will implement it throughout the rest of the country.
I don't know about you, but I think that she may be on to something here.
